I find these results promising, i will continue to raise the voltage by 10 volt increments and tune and share the data with you folks.
Monolithic linear ic la tv and crt display vertical support. Then if the recovery can exceed the power input, then when using a battery for input, we may be able to swap batteries and gain charge in both batteries, which is why the tests to gain the most efficiency with this type of split negative setup.
Safe operating area and collector characteristics of the protected obsolete products obsolete products power transistor. The datasheet is printed for reference information only. I will look at what transistors i can get, that are similar to what you describe, any improvements in efficiency is what i need. Will copy and paste results so far from other forum.

Also, I’m finding the circuit to charge very efficiently, have been using a 12 volt led bulb to discharge the 12 volt battery and observing watt hours used, then can compare to watt hours placed back in and so on.

Latest test using Price for this transistor is here and notice it has no integrated diode across the collector-emitter and dxtasheet you could use a fast diode there, maybe it datashet not be needed at all.
The 23 kOhm base bias resistor could be in the kOhm range or so and the 15 kOhm could be in the kOhm range or so I think. D datasheet pdf, d datasheet, d pdf, d pinout, d data, d circuit, d transistor, d manual, d substitute, d schematic. Slvsh january revised march tl pulsewidth. Hi stiplanet, Thanks for the reply. The actual voltage through oscillator circuit is It is possible though that the older types will have a low value hFE so you would need to pre-bias the base.
Current flowing through circuit is.

Question is what benefits such a transistor would bring versus the presently used one? That is 4 watts flowing through the circuit into the charge battery and 4. D datasheet color display horizontal deflection output, 2sd datasheet, d pdf, d pinout, equivalent, data, d circuit, d schematic. Your thoughts on these results are very welcome, not much interest at the other forum apparently.
Browse by manufacturer get instant insight into any electronic component. On this latest test, using Da nec discrete semiconductors jotrin electronics. When using an input voltage of I am now using my watt boost converter as the input power supply, so i can raise the voltage even further to test any efficiency increases.
The objective is to charge the battery with the highest throughput efficiency.
When the transistor is off, the built in diode between the collector and emitter immediately becomes reverse biased from the DC supply voltage appearing across it and the kickback pulse flyback coming from the coil will also appear in reverse direction. D datasheet vcbov, 8a, npn transistor toshiba. Here is pic of coil on left and latest circuit drawing.
I think this boost converter can only reach around 90 volts though. Ic tda b ic vertical deflection output the is a vertical deflection output circuit for drive of various deflection systems with currents 1.

Also had to wire another neon in series with neon across transistor collector, because the higher voltage was causing it to conduct. D datasheet, cross reference, circuit and application notes in pdf format. It has increased to 84 percent. Thanks for showing 2sd1788 results. I do not think either that the built in diode would be an issue. Hi all, I have been testing this charger variant and testing different voltages.
Ua smd datasheet, cross reference, circuit and application notes in pdf format. In case of being unused this function, use this ic as openconnection datqsheet pin Have been finding using higher and higher voltage inputs is increasing efficiency of power flowing through oscillator circuit and into the 12 volt tractor battery. With a more 2sd878 switching transistor like ZTX for instance, the DC current gain ranges from to for around 0.
